This new study led by Louise Arnold, PhD (LCI Arky Awardee, 2014) from the University of Missouri-Kansas City School of Medicine (UMKC) sought to identify medical school factors perceived as contributing to the leadership development of UMKC graduates who are now in major leadership positions. This study offers guidance from theory and practice for medical schools to consider in shaping leadership education: namely, informal leadership preparation coupled with extensive longitudinal clinical education in a nurturing, authentic environment can develop students effectively for leadership in medicine.
